FLIER AND METHOD OF MAKING THE SAME.

Application filed june 24., 1922. Serial No. 570,648.

To all whom it may concern:

Be it known that I, HENRY SAHLIN, a citizen of the United States,residing in Boston, in the county of Suffolk and State of Massa- 5chusetts, have invented an Improvement in Fliers nd Methods of Makingthe Same, of which the following description, in connection with theaccompanying drawings, is a specification, like characters on thedrawings representing like parts. I

This invention relates to fliers for use on roving and twisting machinesof the character shown and described in United States Patent No.1,393,356 dated October 11, 1921, wherein a hollow sheet metal memberhaving a longitudinally extended slot is welded to a solid metalmember.I I I The present invention has for'its object to produce in a novelmanner as will be described 21. less expensive flier of the characterdescribed. I II I I The particular features of this invention will bepointed out in the claims at the end of this specification. I I

Fig. 1 is a front elevation of a flier produced in a novel manner andembodying the invention.

Fig. 2, a side elevation of the hollow member shown in Fig. 1. I

Fig. 3, a plan of a solid metal or forged blank in its rough condition.

7 Fig. 4, a cross section of the forged blank taken on the line 4-4,Fig. 3.

Fig.5, a plan of the forged blank shown in 3 trimmed or cut to the shapedesired. I

Fig. 6, a side elevation on a larger scale of the forged blank shown inFig. 5 in its folded position.

Fig.7, a cross section of the forged blank in its partially closedposition.

Fig. 8, a detail in'plan ofaportion of the sheet metal blank injuxtaposition to the end portion of the forged blank preparatory to Ibeing welded thereto.

Fig. 9, a view like Fig. 8 with the parts welded togethen'and Fig. 10, aview like Fig. 9 with the weld smoothed and cleaned. The-flier hereinrepresented comprises the essential elements of the flier shownin thepatent referred to, in that it is provided with a solid metal member ahaving the substantially straight arm 10, the curved arm 12, thesupporting member 13 for the hub o, the curved arm 14 extended from thesupporting member 13, and a hollow sheet metal member b welded to thecurved arm 14 and pro vided with a longitudinally extended slot 25.

The flier herein shown difi'ers from the flier shown in the patentreferred to, in that in the present instance portions of the forgedblank from which the curved arm 14 is formed and which were trimmed orcut oil in making the curved arm 14 shown in the patent, are inaccordance with this invention utilized "for for'mingthe curved upperportionof the hollow arm, and for forming the upper art of the slot 25,and the straight portion or the hollow arm I) is formed from a sheetmetal member which. is welded For otherwise firmly connected at itsupperend to the lower end of the curved arm 14 and is provided with a slotwhich forms the lower portion of the slot 25. I I

As a result, the slotted hollow arm 6 ofthe finished flier is acomposite arm, in that it is composed of a hollow solid metal upperportion or member provided with a longitudi nally extended slot, and asheet metal lower 1 portion or member provided with a longitudinallyextended slot, which forms with the slot in the solid metal upperportion a continuous slot for the length of the hollow arm. In formingthe composite hollow arm I), a solid metal blank is first forged intosubstantially the'shape shown in 3, so as to crudely form thehub-supporting member 13, a portion of the curved arm 12, the curved arm14 having the longitudinally extended central groove 30 and thesubstantially wide side fins 31, 32. I I

In addition. the curved rm 14is provided I on its under sidewith a lug.33, indicated by dotted lines in Fig. 3. f

' The forged blank while hotis then cut or trimmed to provide the blankwith the straight end 34, and to convert the fins 31, 32,'into taperingwings 35," 36 (see Fig. 5),

which are of suflicient width to enable them to be ultimately foldedwith the edges slightly separated and thus form the slotted tubularupper portion or member 37 of the hollow arm Z), which is shownseparately in Fig. 6.

The wings 35, 36, while hot are first folded into the form of a U, asrepresented in Fig. 7, and its edges are squared on the line 38, andwhile in this form it has firmly secured to its lower or free end aU-shaped sheet metal member 39, which is formed from a flat metal blank,preferably of cold rolled sheet steel. The U-shaped sheet metal member39 is arranged in juxtaposition to the end of the solid metal member 37after the manner represented in Fig. 8, and is firmly united therewithby welding it thereto, the metal of the weld being represented by 40 inFig. 9.

After the sheet metal member 39 has been welded to the solid metalmember 37, the composite, partially folded hollow arm is then smoothedand polished on its inner and outer surfaces to remove the surplus metaloftheweld and also any scale, burrs and the like, and provide the hollowarm with a perfectly smooth and finished interior as represented in Fig.10, after which the sides of the U-shaped composite metal arm are foldedor closed in to -form the tubular hollow arm 7) shown in Figs. 1 and 2,and the longitudinally extended slot 25 therein.

The lug 33 on the solid metal upper member lat of the hollow arm ismilled or cut to form the projections or ears 21, 20, which form themounting for the usual presser arm not shown.

From the above description, it will be seen that by forming the hollowarm 6 of a solidmetal upper member orportion, and a sheet metal lowermember or portion. a

, less expensive flier is produced, as the cost of filling in the jointsbetween the sheet metal member I) and the curved arm 14 of the fliershown in the patent referred to, is avoided.

Furthermore, in thepresent case. the formation of scale on the interiorof the hollow sheet metal member formed by the welding of the upperportion of the sheet metal member Z) of the patented flier to the curvedarm 14 thereof, is avoided, as is also the scale due to the welding ofthe lower presser mounting lug or ear 20 to the sheet metal member, andas a result the necessity of sand bla-stin the inner side of the sheetmetal member to remove this scale before polish- 12 of the solid metalmember, which counterbalances the hollow composite metal arm or membermay be integral with the blank shown in Fig. 3 or they may be weldedthereto.

The hub-supporting member 13 is shown solid in Fig. 3, but it will beunderstood that it is suitably bored to receive the hub.

In the finished flier the joint between the sheet metal portion 39 andthe solid metal portion 37 is obliterated in the polishing and finishingprocess and is practically not discernible, but for. convenience isindicated on the drawing in Figs. 1, 2 and 10, by the dotted line 45.

Claims:

1. In a flier,.in combination, a hub-supporting member, a hollowcomposite metal arm attached thereto and comprising a longitudinallyslotted solid metal upper portion integral with the-hub-supportingmemher and a longitudinally slotted lower sheet metal portion firmlyconnected with said solidupper portion with their slots in communicationwith each other, and a counterbalancing member for the composite hollowarm attached to the hub supporting member.

2. In a flier, in combination, a hollow composite metal arm having alongitudinally slotted solid metal upper portion and a longitudinallyslotted sheet metal lower portion firmly connected with said solid metalupper portion with their slot-s communicating with each other. V

3. In a flier, in combination, ahollow composite metal arm having alongitudinally slotted solid metal upper portion provided with earsintegral therewith and spaced apart to form a presser mounting, and alongitudinally slotted sheet metal lower portion having its upper endwelded to the lower end of the solid metal upper portion with its slotforming an extension of the slot in said upper portion.

4. In a flier, a hollow metal arm having a solid metal upper portiontapering from its upper end toward its lower end and provided with alongitudinally extended slot, and having a sheet metal lower portionwelded at its upper end to the lower end of said solid metal upperportion and provided with a longitudinally extended slot forming acontinuation of the slot in said upper por tion.

5. The method of making fliers having a composite longitudinally slottedhollow metal arm, which consists in forging a hubsupporting memberwithan arm having substantially wide side fins, trimming the said fins toform tapering side wings, firmly securing a sheet metal member to thelower end of said arm, and folding the solid metal wings and the sheetmetal member to form the composite hollowmetal arm and provide the samewith a slot extended longitudinally in both members of said compositehollow arm.

6. The method of making fliers having a composite hollow metal arm,which consists in providing a solid metal arm with side wings, firmlysecuring a sheet metal member to said arm, and folding the solid metalside wings and said. sheet metal member to form the composite hollowmetal arm and 10 to provide the same with a longitudinally extendedslot.

In testimony whereof, I have signed my name to this specification.
